\JOINTED GUN-STOCK.

Specification of Letters Patent.

Patented Feb. 5, 1907.

Application filed October 4, 1908. Serial No. 337,383.

To (tZZ whom it may concern.-

Be it known that I, HOMER W. MUNsoN, a ci ren of the United States of America, resloing at Wllli'amsburg, in the county of Ham,.ishire and State of Massachusetts, have invented anew and useful Jointed GunStock, of which the following is a specification.

My invention relates to improvements in jointed or adjustable gun-stocks, and more particularly to the kind of jointed or adjust-- able gun-stock set forth in United States Letters Patent No. 824,505, issued to me June 26, 1906; and said invention comprises two stock-sections connected by a hinge of peculiar construction, such hinge consisting of two disks let into said sections and fastened to one of them, a center block fastened to the other section, a pivot-pin for said disks and center block having bearing-heads, a locking-pin, and certain auxiliary parts, all as hereinafter described.

The object of my invention is to produce a strong, durable, and rigid jointed stock for firearms which can be easily and quickly adjusted to change the relation of the stocksections to each other, the same being simple both in construction and operation and consisting of few parts so arranged as to obviate any liability to get out of order. I attain this object by the means illustrated in the accompanying drawings, in which+ Figure 1 is a side view of the major portion of a gun-stock embodying my invention, one of the adjustments being shown in full lines, a second adjustment in dotted lines, and a third in dot-and-dash lines Fig. 2, a view of the end of what I term the butt-section, which is adjacent to what I term the forestock section of said gun-stock, the disks being out through vertically and the connecting pivot-pin being in elevation; Fig. 3, a central longitudinal vertical section through the parts as shown in full lines in Fig. 1, and Fig.4 a central longitudinal horizontal section through said parts.

Similar figures; refer to similar parts throughout the several views.

The stock whichl'use comprises two sections, one of which is herein termed the fore-stock section and is represented at "1 and the other oi which is herein termed the butt-section and is represented at The fore-stock section 1 and the butt-sect1on 2 have their adjacent edges cut away sufiiciently to allow for whatever movement relative to each other it is desired to provide, and

' said members are cut out on the interior to accommodate two disks 3. The disks 3 are securely fastened to thc forestock section 1 by means of screws 4 inserted in said forestock section and passing through holes in said disks. The segments of the disks 3 which are opposite those held by thescrews 4 are received loosely in the butt-section 2. These disks are spaced apart to receive a center block 5 between them, and central openings are made in said disks and center b ock for the reception of a pivot-pin 6. In each disk 3 opposite the holes provided for the screws 4 are three openings7. An opening 8 is so located in the butt-section 2 as to be caused to aline with either pair of openings 7 when the parts are properly assembled and the stock-sections are turned on their pivot or either is turned thereon.

The center block 5 is provided with an upwardly extending arm 9, which is attached between the fore-stock section 1 and the butt-section 2 to the upper part of the front face or edge of said butt-section by screws 10 and 11 11, and said center block is further provided with a rearwardly-extending lug 12, which is received into a chamber 13 in the butt-section and has an opening 14 therein in line with the butt section opening 8. The front part of the center block 5 fits into and is adapted to turn in a suitable concavity in the fore-stock section between the disks 3. The pin 6 has a large integral bearing-head 15 at one end and a similar bearing-head 16 at the other end, except that said head 16 is removable from said pin, since it is ada ted to be screwed on and off of the threads terminal 17 of the pin which is opposite said head 15. When the pin 6 is in place in the disks 3 and in the center block 5 and the head 16 is screwed onto said pin and tightened with a spanner-Wrench or other suitable t0ol, the two bearing-heads 15 and 16 are held firmly against the outer sides of said disks and the two stock-sections are securely hinged together. he center block is now free to turn on the pivot-pin or said pin is free to rotate in said center block, as the case may be, or both actions may be had if both stocksections are manipulated at the same time. The heads 15 and 16 fit into concave recesses in the two stoek-sections and afford additional bearings for said sections.

From the foregoing it will be seen that in adjusting when the stock-sections are pivoted together. the fore-stock section 1 rides IIC . place in the manner and by the means ascribed below a very rigid -and practically ibreakable joint is the result" 4 To secure the parts after adjustment, I nploy a locking-pin 18, which is adapted pass through the opening 8 in the buttction.2, any pair of-oppositely-disposed )enings 7 in the disks 3, and the opening 14 the center block 5., the sides ofsaid opening and the portion 19 of said locking-pin hich enters such opening and remains .erein preferabl being screw threaded.

1e inner end of t e locking-pin l8 mayeX- i nd beyond the ad jacent disk 3 into the butt- I ction. More orless than three pairs of -enings 7 in the disks 3 may be provided, the

lrnber of different adjustments being varied cordingly, since each of such pairs perits one adjustment. The centers ofthe enings 7 as well as of abutting curved airing-surfaces, are concentric with the axis the pin 6'.

Recesses in the head 16 for the engaging ejections of a spanner-wrench are repreited at 20, I Qne ofvthe'ext reine positions of adjustment rmitted in-this construction is illustrated full linesin. the first view, the other care ine position is-there indicated by the'dotdash lines 21 and the intermediate posin by the dotted lines 22. The change 'm anyone of these positions'to another effected by withdrawing the locking-pin,-

riing the pivoted parts upon their pivot,

whatever extent may be necessary to obn the required relation 'or angle, and tin inserting .said locking-pin, care being, arcised to bring the openings 7 which are to used into line with the openings 8 and 14.. in order to separate the stock-sections,

iply take out the locking-pin, unscrew the id"16, and remove the pivot-pin.

Various ch anges in the arrangement and LStIHCtlOIl of some oral] of the parts of my ice will readily occurv t6 one skilled in the and such changes which fairly fall within scope of my claims I desire to include in invention.

Vhat I claim as my invention, and desire ecure by Letters Patent, is

. The combination, in a jointed gun-stock,

h a stock-section provided with disks fas- 2d thereto and projecting beyond, the

-tened thereto and projecting same, of a second same, of a second stock-section adaptedto receive portions of such disks and provided with a center block fastened thereto and arranged to enter between said disks, and a piv-' otal connection between the disks and center block.

2;. The combination, in a jointed gun-stock,

with a stock-section-provided with disks fas stock-section adapted to receive portions of such disks and provided with a center hlockfastened thereto and arranged to enter between said disks, a pivotal connection between the disks and center block, and a locking-pin adapted to secure saidcenter block and the stock-section to which the latter is fastened and the disks together.

3 The combination, in a jointed gun-stock, with a stock-section provided with disks fastened thereto and projecting beyond the same, such disks having a plurality of openings therein for a locking-pin, of a second stock section adapted to receive portions ofi said disks and provided with a center block fastened thereto and arranged to enter betweenvthe disks, a pivotal connection between the disks and center block, the stock section to which said center block is secured and such center block having alining openings therein with which the disk-openings may bewbrought into alinement as the parts are-z-t urned on their pivot, and a locking-pin adapted to enter whatever openi'n s are in alinement and secure the disks to t .e center block and its stock-section.

g 4; The combination, in a jointed gun-stock, with a stock-section provided with disks fastened. tiereto and projecting beyond the same, of a second'stock-section adapted to receive portions of such disks and provided with a center block fastened thereto and ar ranged to enter between said disks, and a.

beyond the ICO pivot-pin; connecting the disks and center block and provided at the, ends with i'eads which afford bearings for contiguous parts of tlr e two stock-section's.
